Abstract
Ascorbic acid and substituted ascorbic acids can be reacted with a tetraorganosilicate such as a tetraalkylorthosilicate to yield a product which contains silicon. The products are generally solid in nature, and typically they are insoluble without hydrolysis. The products are useful as active agents in the prevention, treatment, or delaying of the onset of calcium-related bone disease such as post-menopausal osteoporosis.
